Monster Regret!!

Whatever you may think of Noel Lee’s engineering and/or or marketing genius, He did delegate the Monster Power design project to Richard Marsh...author of the 1980 Audio Magazine article that announced to the world that the design and composition of capacitors matter to the sound quality of electronic components, an idea that utterly transformed the audio landscape, heralding the modern high end as we know it.  Richard, in return for lending his expertise and credentials to Monster Power, got funding to launch his own company that produced some great sounding electronics based on his capacitor work. Long gone. 

Monster made decent equipment. nothing wrong with it.  There are better equipment out there and also worse.

A point of clarification, Ground Loops are not caused by connecting to different outlets.  Ground loops are caused (mostly) by poorly designed/constructed equipment that do no incorporate proper grounding techniques.  Lack of proper cable shielding, etc.  If outlets are connected properly and to code, then the home grounding schemes are correct.  Sometimes outlets and boxes are not grounded properly.  That is a different issue.

In my family room where the TV/home theater system is located, I still use my trusty Monster Signature HTPS-7000 unit.

for my 2 channel listening room, I ran four separate dedicated lines.  each dedicated line has it's own hot, neutral and ground that is not shared with any other circuit and is run all the way back to the service panel.  

My amps are plugged directly into their own dedicate wall outlets.  The low level equipment (pre-amp, tuner, DAC, Turntable power supply, Electronic Crossover, Music Server, CD Transport) are all plugged into a Transparent Audio Power Conditioner, which is in turn plugged into it's own dedicated line.

I have done direct comparisons with and without the power conditioner and also before and after with the dedicated lines, and my noise floor dropped substantially. it is extremely silent.  

In any case, for the money, Monster projects are just fine.  Also, all manufacturers have some form or another of hype in marketing their products.  Monster is no different.

Actually connecting to different outlets is a text-book definition of the cause of a ground loop, and much of what you described is not or at least cannot be called specifically a ground loop.

A ground loop is by definition having multiple paths for ground currents to flow such that the reference ground voltage is not the same between pieces of equipment and when that ground is used for a signal reference, that can lead to line-frequency hum, or signal injection due to ground injection from power supply transients, etc.

There are always multiple points of ground connection, i.e. interconnects, and where the AC grounds connect together. It is better to have those ground connect together as close as possible for all equipment, not back at the junction box 50 feet away.

No matter what it is your testing or considering for your audio system , always hear before commiting and let your ears and TASTE make the final decision .

Take your time . Listen while you are relax and in a good mood . Sometimes that which might be considered a small and subtle difference on long term listening might actually be ( because of our ears incredible hearing acuity ) very audible . 

But the bottom line is to take your desicion based on your ears and taste 
 .
On the subject of equipment design to protect your investment there are many on the market that will do it . As long as it doesn't have detrimental effect on the sound your'll be ok . Many even makes your system sound better . I've never personally tried a Monster Cable line conditioner or protector but have talk to some buddies who have which I trust and all say they work and don't have a negative impact on the sound . 

So as long as they protect and that is what your looking for Monster is ok . To finish I would like to recommend what I use which not only has protected my system but has cause a large step forward in sound quality for all the pieces in my system including my power amplifier . It is a Richard Grey product . if you can audition one of their products do so . By what I've read they don't always work for a better sound ( system dependent ) but when they do owners are extremely satisfied . Take care .

I also bought an HTS 5000 when they were new. I remember hooking it up and noticing a definite improvement in the sound. I was living in an apartment at the time with a mid-fi set up. I currently have a bedroom system plugged into it- Sony TV, Sonos Beam and Sub, etc. It's still working. 

Back in the day, Monster Cable was revolutionary with their thick speaker wire at $1.00 per foot. I also still have some of their M-Series cables which were pretty good, but they don't compete with AQ for sound quality. They do hold up better over time, though, as they don't fray and their outer casings don't pull away from the tips.
